MODE 0F CONSTRUCTING BEDSTEADS.

Specicaton of Letters Patent No. 1,504, dated March 8, 1 840.

To all 'whom 'it may concern:

Be it known that I, J oHN HART, of. Lebanon, Marion county, and State ofKentucky, have invented a new and useful Improvement in the Art ofMaking and Constructing Bedsteads; and I do hereby declare that thefollowing is a full and exact description of the same.

'Ihe na-ture of my invention consists in extending the shoulders of therails above the periphery of the rails, where the cord or sacking isatt-ached1 so that the cord or sacking is 'then brought to draw in thetight will keep the post up lirm againstthe shoulder .without the aid ofscrews or other fastenings, the top of this shoulder being nitches so bythe aid of a lever you mayv turn the rail till the sacking becomesperfectly tight, and by means of those catches kept fast to the pointturned to. When you wish t-o dispense with lthe tightening-ot' thesacking by turning the rail with the lever those catches are dispensedwith and the same issecured by means of a dowel pin.

To enable others, skilled in the art, tok

make and use my improvement,.I will describe the construction andoperation of my new improved bedstead. For fuller specification I shallrefer as I proceed to the drawings herewith inclosed.

My improved bedstead is made and constructed like ordinary lbedsteads,except in those parts which I will now proceed in detail to describe.

The rails are turned around, but may be ot other forms and the tenonsare turned around being formed on the ends of the rails or inserted intothem. In order to make the extended shoulder a piece of plank isprovided 7 or 8 inches long a little greater in breadth than thediameter of the rail and one inch or upward in thickness and there has ahole bored through the size of the tenon of the rail which tenon passesthrough this hole sufficient to enter the post; this piece is glued andnailed to the rail in this manner, this piece forming the extendedshoulder. When it is intended that the rails remain permanent a smalldowel pin is i11- serted in this shoulder near the top which enters thepost in addition to the tenon of the rail to keep the rail fromturning'in when drawn by the sacking attached to the upper surface. Forthis shoulder see drawy drawings.

ings sec. 2 and letter A; for the dowel pin same section, letter B, andfor tenon same sec. letter C, and for this shoulder and rail when framedup to the post see sec. 1, letter O.

When it is intended that the rails should turn for the purpose oftightening the cord or sacking, the dowel pin isdispensed with and theiron catches are adopted, the shoulders are made as above stated but arein addition tapered from the outside of the rail to the top near to apoint; on the inner edge of them is fastened by two screws a plate ofcast iron lginches long l inch broad and inch in thickness which extendsinch above the shoulder, the same standing a littlein, and isbeveled 0Hto an edge from the outside to serve as acatch to aplate of cast ironwhich extends horizontally above itiand rests upon it. For a fullerillustration of this shoulder and the plate of cast iron attached toitsee drawing sec. 3, letter D, and for the manner of its application tothe post see in drawing sec. l and let-ter E. Above this shoulder thereis a plate of cast iron about et inches long inch broad i thick, seedrawing sec. l and letter X. One end of this plate is screwed to thepost near its outer corner see the end of plate letter X. Near letter P,indrawings, its opposite end rests upon shoulder E, seen in sec. 1st ofIts lower edge lis lled with nitches so formed that they offer no resistance to the said shoulder as it is turned out; but prevents it fromturning in by falling on th-e catch.

Vhen this bedstead is put up the catches v upon the top of the shouldersare placed in the innermost nitch of the horizontal plate and then thecord o-r sacking is put on. The process of tightening the sacking is byinserting a lever in the rail, a hole being there for that purpose .asseen in drawing sec. l, and letter R, by thelever you turn the railoutand as it turns out it catches in more remote nitches and isprevented from turning back.

What I claim as my invention and desire to secure by Letters Patentis.--

The extension of the shoulder beyond the periphery of the rail in themanner and for the purposes herein described.

JOHN HART.
